Extract toxic gases
Combustion processes - for example cars moving around in an enclosed parking garage - release toxic gases like nitrogen dioxide (NO2) and carbon monoxide (CO). In order to maintain an adequate health and comfort level, the concentration of these toxic fumes must be monitored so that fresh air can be supplied in time. This HVAC transmitter measures temperature, relative humidity, CO, NO2 and ambient light level. Based on the temperature and humidity measurement, the dew point is calculated. All these values are available via Modbus RTU communication. The sensor algorithm can directly control an EC fan, an AC fan speed controller or a damper actuator via Modbus RTU communication. The output value varies proportionally in function of the measured temperature, relative humidity and CO level. E.g. as temperature, relative humidity or CO level approaches their maximum limit, fan speed will increase or the damper will open.
Reduced installation time
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. Most 24 VDC power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
This sensor doesn't require any configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU. For example, the temperature or relative humidity range can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is heat resistant, solid and offers good protection against impacts. It offers an IP65 protection against ingress of dust and water. Each sensor is calibrated and tested in our factory. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. To ensure optimal performance, it should be protected from direct sunlight.
